[0045] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that the drawings are for illustrative purposes only and should not be construed as limiting the scope of the present application.

[0046] It should be noted that similar reference numerals refer to similar items throughout the accompanying drawings, and where the context allows, the same reference numerals will be used in the multiple drawings. The drawings provided herein are included for illustrative purposes and the patentability of the claimed subject matter is determined by the written description and claims, and not necessarily the accompanying drawings.

[0047] As shown in Figure 1 and Figure 2 , a clothes drying machine 100 capable of displaying the weight of clothes includes a main machine 10, a drying rod 20, and a drive device 30 for retracting and releasing a steel wire rope. The drive device 30 is arranged in the main machine 10, and the steel wire rope s drawn from the drive device 30 is connected to the drying rod 20 after passing through a pulley 40. The drive device 30 drives the steel wire rope s to release or wind, so as to drive the drying rod to rise and fall.

[0048] Preferably, the drive device 30 includes a high-efficiency motor and an intelligent control system to realize smooth and energy-saving lifting operation. The steel wire rope s is made of high-strength material and is specially treated on the surface to reduce friction and wear. The pulley 40 adopts high-precision bearings to reduce noise and improve self-cleaning ability. The drying rod 20 is foldable or telescopic, and the surface is treated to prevent slipping to ensure the safety of clothes.

[0049] It should be noted that the clothes drying machine 100 capable of displaying the weight of clothes provides a user with an intuitive way to monitor the weight of clothes on the drying rod 20 through a weighing system 200. The weighing system 200 is composed of a weighing module 201 and a display 202, wherein the weighing module 201 is responsible for measuring the force acting on the pulley 40, and the display 202 clearly displays the measurement data, allowing the user to know the weight of clothes in real time. Not only does it improve the practicality of the clothes drying machine, but also increases its safety, because the user can adjust the clothes according to the displayed weight to avoid exceeding the maximum load of the clothes drying machine, thereby protecting the motor and prolonging the service life of the equipment.

[0050] The working principle of the weighing module 201 is to connect the pulley 40 and the weighing system through a pin shaft 41, which not only supports the pulley, but also transmits the tension of the steel wire rope s to the weighing module. The display 202 is installed on the lower surface of the main machine 10 for the user to view.

[0051] Specifically, as shown in Figures 3 to 6 , the weighing module 201 includes a cover assembly 50 and a conversion device 60, which ensures the accuracy and reliability of the weighing process.

[0052] The cover assembly 50 is composed of a weighing upper cover 51 and a weighing lower cover 52, and a weighing spring 53 is arranged between the two, which helps to balance the tension transmitted by the pulley 40 and ensures the accuracy of measurement. The weighing lower cover 52 is fixed on the main machine 10, providing a stable support for the entire weighing module.

[0053] The display 202 includes a weight scale dial 71 and a pointer 72, which is intuitive and easy to read, and users can quickly understand the current weight of the clothes. The weighing upper cover 51 is integrated with a pulley 40, which is in direct contact with the steel wire rope s and is responsible for transmitting the tension of the steel wire rope to the weighing module 201, which is a key link in the measurement process.

[0054] The conversion device 60 is the core of the weighing module 201, which includes a screw rod 61, a rotating main shaft 62 and a rotating secondary shaft 63. The screw rod 61 is fixed to the bottom of the weighing upper cover 51 and is connected to the rotating main shaft 62 through threads, which can accurately convert the small movement of the screw rod into the rotation of the main shaft. The rotating main shaft 62 is engaged with the rotating secondary shaft 63 through a gear assembly 80, which ensures the efficiency and accuracy of force transmission. The bottom end of the rotating secondary shaft 63 is fixedly connected with the pointer 72, which directly responds to the movement of the screw rod 61 and drives the pointer to rotate on the scale dial.

[0055] When the pulley 40 is subjected to the tension of the steel wire rope s, the screw rod 61 will move downward, driving the rotating main shaft 62 to drive the rotating secondary shaft 63 in the first direction, causing the pointer 72 to rotate to the corresponding weight scale, thereby displaying the current weight of the clothes. When the pulley 40 is not subjected to the tension of the steel wire rope s, the weighing spring 53 will play its role, driving the screw rod 61 to move upward, causing the rotating main shaft 62 to drive the rotating secondary shaft 63 in the second direction, causing the pointer 72 to return to its original position, preparing for the next measurement.

[0056] This technical means not only improves the functionality of the clothes dryer 100, but also enhances its durability and user-friendliness. By combining modern mechanical engineering with intuitive display technology, the clothes dryer 100 provides users with a practical and reliable solution to ensure that they can accurately control the weight when drying clothes, avoid overloading, protect the motor and prolong the life of the equipment.

[0057] More specifically, as shown in Figures 7 to 9 The gear assembly 80 is the key to connecting the rotating main shaft 62 and the rotating secondary shaft 63, consisting of a first gear 81 and a second gear 82, which are respectively installed at the bottom end of the rotating main shaft 62 and the upper end of the rotating secondary shaft 63. This layout makes the force transmission more direct and efficient, ensuring the sensitivity and accuracy of the weighing module 201.

[0058] The upper end of the rotating main shaft 62 is open and has a vertical thread hole 621 inside, which matches the thread 611 at the bottom end of the screw rod 61. This threaded connection not only ensures the stability of the structure, but also makes the force transmission between the rotating main shaft 62 and the rotating secondary shaft 63 more accurate. This precise thread matching allows the small movement of the screw rod 61 to be accurately converted into the rotation of the rotating secondary shaft 63, thereby driving the pointer 72 to accurately indicate the current weight on the scale dial 71.

[0059] The supporting walls 511 on both sides of the upper cover 51 of the scale are ingeniously designed, which not only provide support for the pulley 40, but also fix the pulley in place through the pin shaft 41, ensuring stable contact of the pulley with the steel wire rope s and accurate transmission of tension information. The lower cover 52 of the scale is fixed on the main machine 10, providing a solid foundation for the weighing module, and the display 202 is installed on the lower surface of the main machine, facilitating the user to view the weight information during operation.

[0060] The first gear 81 and the second gear 82 of the gear assembly are arranged in the gear box 90, which is fixed on the main machine 10, providing additional protection and stability, ensuring reliable operation of the gear assembly in various environments. This packaging technique also helps to reduce dust and moisture intrusion, prolonging the service life of the gear assembly.

[0061] The sinking amount of the upper cover 51 of the scale is equal to the compression amount of the spring 53, which ensures that the weighing module can be automatically zeroed when there is no load, improving the repeatability and accuracy of the weighing. The pointer fixing pin t fixes the pointer 72 and the rotating secondary shaft 63, ensuring stable movement of the pointer when the load changes, avoiding pointer jitter caused by vibration or impact, and improving the stability and reliability of the reading.
